Presented at
DEF CON 30 (2022),
Aug. 12, 2022, 6 p.m.
(45 minutes).
Governments and the private sector around the world spend billions of dollars on Electronic Counter Measures (ECMs) which include jamming technologies. These jammers are used by police departments to disrupt criminal communication operations as well as in prisons to disrupt prisoners using smuggled in cell phones. The military use jammers to disrupt radar communications, prevent remote IEDs from triggering and radio communications. The private sector use jammers to disrupt espionage in the board room and to protect VIPS from RC-IEDs.
What if there was a way of communicating that was immune to jammers without knowing the point of origin. A way of communicating at short to medium distances, an Electronic Counter Countermeasure ECCM to the jammer.
Using a custom-built Tx/Rx, I will use the earth’s crust to generate a H-field Near Field Communication (NFC) channel spanning 1-11km away in the sub 9 kHz range to communicate encrypted messages in a jammed environment.
